In the wake of the recent database hacks, i.e. Sony, Gawker, etc.. where the hackers have access to the hashed usernames and passwords, i've been more keen in paying attention to the sites and services i regularly use, and am paying more attention to how my data is stored. I know that Gawker used DES, i believe, to encrypt their info, which is not as effective as a newer method such as AES.

So do we know what encryption type Google uses or how many rounds of salt they use for their services?
